ubiquity announced a similar productline too (THOUGH-Switch). Specifications?
There is a 5 port 24V or 8 port 24/48V version, and they might have no problem in powering/switching 20W boards (or at least an N2800MT should work)

but gpio only available with unsolder/reuse led, caution there are 16/4 and 32/8 (RAM/Flash) variants!
